Short Answer:
Write a sentence or a short
paragraph to answer each of the
following questions.
What is the distance from the Sun to
Mars in kilometres?
1 AU = 150 000 000 km
Mars = 1.4 AU from the Sun
What is the distance from the Sun to
Mars in kilometres?
1 AU = 150 000 000 km
Mars = 1.4 AU from the Sun
= 1.4 AU x 150 000 000 km
= 210 000 000 km
The distance from the Sun to mars
is 1.4 AU. The distance from the
Sun to Jupiter is 4.48 AU. How
much farther away is Jupiter from
the Sun than Mars in kilometres?
The distance from the Sun to mars
is 1.4 AU. The distance from the
Sun to Jupiter is 4.48 AU. How
much farther away is Jupiter from
the Sun than Mars?
Jupiter is 4.48 AU - 1.4 AU
= 3.08 AU
= 3.08 AU x 150 000 000 km
= 462 000 000 km
Calculate the length of one day on
Uranus (in Earth-hours) if Uranus
rotates in 0.72 Earth-days.
(1 Earth-day = 24 hours)
Calculate the length of one day on
Uranus (in Earth-hours) if Uranus
rotates in 0.72 Earth-days.
(1 Earth-day = 24 hours)
Day on Uranus
= 24 hours/Earth-day x 0.72 Earth-days
= 17.28 hours
How long is one year on Venus in
months if one year on Venus is
0.60 Earth-years?
(1 Earth-year = 12 months)
How long is one year on Venus in
months if one year on Venus is
0.60 Earth-years?
(1 Earth-year = 12 months)
One Year on Venus
= 12 months/Earth-year x 0.60 Earth-years
= 7.2 months
If you were 17 years old on Earth,
how old would you be on Venus?
If you were 17 years old on Earth,
how old would you be on Venus?
On Earth
= 17 years x 12 months/year
= 204 months
If you were 17 years old on Earth,
how old would you be on Venus?
On Earth
= 17 years x 12 months/year
= 204 months
On Venus (One Year is 7.2 months)
If you were 17 years old on Earth,
how old would you be on Venus?
On Earth
= 17 years x 12 months/year
= 204 months
On Venus (One Year is 7.2 months)
= 204 months / 7.2 months/year
= 28.3 years

•solar winds from the new star blow away most of the hydrogen and helium
from the inner regions leaving chunks of heavy matter
•these chunks keep colliding with each other and grow in size to eventually
become the inner planets
• lighter more volatile elements (Hydrogen, Helium) are distributed in the outer
regions forming the outer planets remaining matter makes up asteroids,
